v.121.0.1 BETA

• This is a beta of Mercury for Windows 7 based on 121.0.1
• The patches to enable Win7/8/8.1 support past ESR 115 came kindly from @K4sum1 > https://github.com/Eclipse-Community/vyvfox
• Window frame is a little messed up
• I forgot to set the subsystem version to NT 6.0 (He has it set to Windows 95, which reduces some subsystem featuresets)
